When I try to present EKCalendarChooser to display the calendars, the app crashes every time inside EventKit framework after the latest iOS 14 update. I was seeing this crash in Beta version and was hoping this would be fixed in iOS 14 GM but still the crash seems to be present. The below is a simple code to present EKCalendarChooser. I have tried subclassing as well both the approaches work in iOS 13 and below and crashes in iOS 14 only - let store = EKEventStore() store.requestAccess(to: .reminder) { success, error in     DispatchQueue.main.async {         let chooser = EKCalendarChooser(selectionStyle: .multiple, displayStyle: .allCalendars, entityType: .reminder, eventStore: store)         self.present(chooser, animated: true, completion: nil)     } } The below is the crash report for the same in iOS 14 - Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<EKFrozenReminderCalendar 0x600003724960> valueForUndefinedKey:]: this class is not key value coding-compliant for the key publishURL.'

It works fine for event. Can someone please help me with any workaround for this, since calendar selection is the main feature within our app.

Hi I'm developing a mobile-app and a web-app that access a user's personal calendar events. From a mobile-app is simple using Apple libraries. From a web-app is different. I found that a calendar can be shared: Publicly: Calendar can be accessed using CalDav (readonly access). Privately: Calendar is shared via another iCloud account. the calendar can now be accessed from this other account (read/write access) My question is, is this the only way i can access an apple calendar without making it public? If i use the iCloud sharing approach, are there any limitations? if i use this approach for very high number of users, will it be allowed by Apple? Thanks

Hi All. Looking for an IOS solution that will automatically add any call I make from my phone to my calendar. This is so I can track call history on my calendar, not track someone else's usage. My questions: What app does this? (couldn't find one in the app store/Google search, if you know of one please do share) Is it even plausible to create an app that would do this? IOW, will IOS allow this type of app functionality? Truly appreciate your feedback! BK

I am trying to retrieve emails from participants in a calendar event. The documentation (https://developer.apple.com/documentation/eventkit/ekcalendaritem/1507140-attendees) states that this information is provided as as an array of EKParticipant objects. But, in reality, I get an array of EKAttendee objet. This object is not documented. It contains the information I'm looking for (email) but I can't find any way to retrieve it. Have you ever faced this problem? How to retrieve the email of the participants?

My standalone watchOS app is trying to read from the calendar via EventKit. It seems to only see local calendars though, not any of my iCloud calendars. Do I have to do something special to be able to view the iCloud based calendars?

Hello, I recently updated my mac to Big Sur and I am unable to use Logisim with it. Is there anything I can do to fix this?

Hello, I am trying to schedule reminder in my app based on my silent push notification received but I'm unable to do so in background or suspended mode.Can anyone suggest a way to do so? My basic purpose is to remind the user at a specific time based on the info received from push notification.Thanks!

I dont see anything in the documentation about how to add Tags in EventKit. Is that available to us to use and I just missed it in the documentation?

Hello All, It appears I've hit a dead-end in developing a "scheduling" app in terms of utilizing the Date Picker control as a calendar that actually functions like the apple calendar. It also appears the EventViewController will only display one event versus an array of events??? So in order to list events/reminders in an app, we have to build this out in a table view or stack view??? I'm finding it hard to believe we can't simulate the current calendar display that when you click on a day, it will display that days events/reminders and have the 7 day view on top of it, etc... Also, I did look at the calendar kit in CocoaPods. I was hoping to build my own using EventKit though. Lastly, I was going to post a screenshot of this calendar/schedule image from an iPhone 11 simulator but it looks like we can't post screen shots in here???

Hi All, I want to build a web application to automatically track calendar invitation status. After searching the forum I already figured out that there is no official apple api to access the calendar data of the user (without asking the user to enter his apple credentials). Luckily there is even a public accessible http endpoint to get the needed information: https://www.icloud.com/calendar/eventreply/?t=<IDENTIFIER>&p=p31&cc=DE This link is included in the email being sent out to the invited people. Navigating to the link shows the invitation status of all people invited to this event. Exactly what I need. Is it okay to use this endpoint for my purpose? Thanks in advance. Best, Jan

Hi, I'm a software developer. I have a web application where users receive event invitations via email. In the email, I would like to have an iCal Calendar icon that when a user clicks it, it opens up the Create Event page within their Calendar. And it would be populated with the data passed in the URL parameters like event start and end date, timezone, title, description, Link to the event, etc. I have already done this with Google Calendar and Outlook Calendar. For example, the Google API URL looks something like this: Add to my calendar Does apple have a link similar this? Or is the only way to create an .ics file and have the User download and import it into their Calendar?
